- Claims 7. (or. 260166.)

It is an object of my invention to provide a process for producing anon-inflammable liquid having great solvent properties, making itvaluable for use asa cleaner or as a solvent for use in the paint andvarnish industries.

exhausting theproduct of the oil deposits. The

dry cleaning industry and the paint and varnish industry are takingupward of three hundred fifty million gallons per year of gasoline andnaphtha which would otherwise be available as motor fuel.

The present invention provides a process that will utilize the otherwisewasted gas to produce a liquid that can be used instead of the motorfuel liquid and therefore prevent the drain upon the available motorfuel oil, at the same time providing as a substitute therefor, for useas a cleaner and as a solvent, a material which is superior to theheretofore used motor fuel in that it is non-inflammable and leaves nodisagreeable odor when used as a cleaner.

The use of the fluid provided by the invention for the purposesindicated will prevent fires and ance with the present invention,carried out under pressure, provide a liquid at atmospheric pressure andtemperature.

In accordance with the invention a closed vat formed of, or lined with,amaterial which is not attacked by HCl and capable of withstanding apressure of two hundred fifty pounds per square inch is provided havinga pipe connection with a condenser and recovery apparatus forhydrochloric acid, the pipe connection being provided with a safetyvalve.

To carryout the process of the invention, the vat is first filled withnatural gas at a pressure of preferably one hundred twenty pounds andnot substantially less than onehundred pounds per square inch, aquantity of antimony or phosphorus pentachloride equivalent to twopercent of weight of the gas having been placed in the vat. Chlorine gasis then injected into the vat at a rate of two and one-half per cent ofthe weight of the gas during the firs'thour; A manometer Withwhich thevat is provided will indicate increase of pressure as a result of thereaction of the chlorine with the hydrocarbon gas.

To keep down the heat produced by the reac tion, the vat has connectedthereto a pump to circulate the gas, or the liquid resultingfrom thepressure and chlorination of the gas, through a cooling coil having aheat exchange capacity to reduce the temperature of the operation tosubstantially 05F.

The safety valve in the outlet pipe for hydrochloric acid should be setto allow-a pressure of substantially one hundred fifty pounds per squareinch.

During the second hour, the chlorine is introduced at a rate ofsubstantially four per cent of the weight of the initially introducedgas, and during the third and fourth hours to five per cent per hour ofthis weight. During the fifth hour, eight per cent of the chlorine gas,and during the sixth hour and continuously thereafter until completionof the reaction, ten per cent of the chlorine gas may be admitted.

The initial weight of the gas in liquid form will be substantially threeand one-half pounds per gallon and the chlorination is carried forward89 until the resulting liquid has a weight of substantially twelve andone-half pounds per gallon which will require the introduction ofeighteen pounds of chlorine per gallon of the resulting liquid, ninepounds of which will have entered into reaction with the hydrocarbon gasand nine pounds will have passed ofi in the form of HCl.

When the reaction is complete, the chlorinated liquid is removed fromthe vat and neutralized with a two and one-half per cent solution of 90NaOH or KOH in water. The neutralized liquid is allowed to separate fromthe alkaline solution, thus providing an excellent solvent, as stated,for use in the varnish and paint industry and a safe and cheap drycleaning material both for commercial dry cleaning establishments or foruse in the home.

Minor changes in the quantities indicated or in the pressures utilizedor in the details of the process may be made within the scope of the ;l0appended claims without departing from the spirit of the invention."

I claim:

1. The process of producing a non-inflammable solvent and dry cleaningagent which com- 9 prises subjecting a mixture of ethane, methane,propane, and'butane gases to chlorine gas while under pressure in excessof substantially one hundred pounds per square inch and in the presenceof a catalyzer for chlorination,

chlorine gas at a pressure between substantially one hundred pounds andone hundred fifty pounds per square inch in the presence of antimonypentachloride. V

4. The process of producing a non inflammable solvent and dry cleaningagent which comprises subjecting natural gas to the action of chlorinegas at a pressure between substantially one hundred pounds and onehundred fifty pounds per square inch in the presence of an- 1 tiinonypentaohloride and maintaining the tem perature of the mixture atsubstantially 0 F.

5. The process of producing a' non-inflammable solvent and dry cleaningagent which comprises placing natural gas and antimony pentachloride ina closed chamber under pressure in excess of substantially one hundredpounds per square inch, injecting chlorine gas into the chamber at agradually increasing rate of introduction and controlling the heat ofreactio by refrigeration.

6. The process of producing a non-inflammable solvent and dry cleaningagent which comprises placing natural gas and antimony penta chloride ina closed chamber under pressure in excess of substantially one hundredpounds per square inch, injecting chlorine gas into the chamber at agradually increasing rateoi introductionand controlling the'heat'ofreaction by'refrigeration and the pressure bypermitting escape of formedI-ICl.

7. The process'of producing a non-inflammable solvent and dry cleaningagent which com 1 prises placing hydrocarbons which are gaseous undernormal pressure and temperature with antimony pentachloride in a closedchamber under an initial pressure of substantially one hundred twentypounds per square inch, gradually injecting chlorine gas into thechamber to an amount of substantially two and one-half per cent of theweight of the hydrocarbon during the first hour, four per cent duringthe second hour, five per cent during each the third and fourth hours,eight per cent during the fifth hour and ten per cent during eachsucceeding hour until chlorination is complete, refrigerating thematerial during reaction and keeping the pressure thereof tosubstantially one hundred fifty pounds per square inch by allowingescape of formed H01.
